Apples

Apples of all varieties and types help suppress hunger for a number of reasons. First, apples are filled with soluble fiber and pectin, which help you feel full. Apples also regulate your glucose and boost your energy level. Finally, apples require lots of chewing time, which helps slow you down and gives your body more time to realize that you're no longer hungry. Plus, they just taste good!

In the same study, those who ate eggs ingested an average of 330 fewer calories over the course of a day than the bagel-eaters. Food for thought, no?

Dark Chocolate

Love chocolate but have no self control with it? Try slowly savoring a piece or two of dark chocolate with at least 70 percent cocoa the next time you crave it. Just a little dark chocolate helps to lower your cravings because the bitter taste signals the body to decrease your appetite.

If dark chocolate is too bitter for you, try having a piece with a cup of black coffee—it'll bring out the sweetness!

Wasabi

Ever notice how when you eat sushi it doesn't seem to take as much food to fill you up? Well, part of that is because of the healthy fish in sushi, but the other part is due to that spicy green stuff: wasabi! The spiciness in wasabi suppresses appetite and is a natural anti-inflammatory.

Green Tea

If you're not a coffee drinker and get sick of water easily, try sipping on a cup of hot green tea. Green tea can help you to stop mindlessly snacking, and nutritionists say that the catechins in green tea help to inhibit the movement of glucose into fat cells, which slows the rise of blood sugar and prevents high insulin and subsequent fat storage. And when your blood sugar is more stable so is your hunger!

Oatmeal

Did this one surprise you? While high in carbs, the type of carbs in oatmeal are slow-digesting and keep you feeling full for hours after breakfast. Why? Because they suppress the hunger hormone ghrelin. In fact, oatmeal is pretty low on the glycemic index—just be sure to make steel cut oats to get the most benefit!

Just be sure to drink the low-sodium varieties, which are less likely to make you bloat.
